Giant pandas enjoy "birthday cake" made of bamboo branches and apples at the Yunnan Wild Animals Park in Southwest China's Yunnan Province, August 12, 2008. The Yunnan Wild Animals Park on Tuesday held a party to mark the second brithday of giant panda "Si Jia". Giant pandas "Mei Qian" and "Qian qian" shared the "birthday cake" for "Si Jia". The three giant pandas were evacuated from a breeding base in Sichuan Province in June to avoid threats from possible geological disasters after the devastating May 12 earthquake.
